Patent GB-857895-A (GB)
Title: Improvements in or relating to methods of making thermal insulation products
IPC: C04B28/18
Filed: 1959-03-20
Abstract: Thermal insulation products are made by casting an aqueous slurry of lime and silica in a mould, partially reaching the slurry to a solid body of self-sustaining form and to an extent less than that necessary for completely curing the slurry, compressing the self-sustaining body to a volume smaller than that of its partially reacted condition and then indurating it to a finally cured condition.  The compression, which has the object of increasing the strength of the body, is suitably such as to result in a reduction in volume of 7 to 13%.  To cast a cylindrical insulation product the slurry preferably in the proportions of from 0,65 to 1 : 1 lime to silica and from 0,75 to 9 : 1 water to solid, is poured into the space between a cylindrical mould and a core, the latter centred in a recess in the mould bottom.  The slurry is maintained in the form of a dispersion by the addition of finely divided fibrous material. Partial reaction is then brought about by steam under pressure. The core is removed and replaced by an oversized core, or an expansible core, enlarging the opening and thereby compressing the partially reacted slurry, which is then indurated under elevated pressure and temperature.

Title: Improvements in or relating to stop motions or signalling devices for knitting machines and the like
IPC: D04B35/10
Filed: 1940-06-07
Abstract: 541,729. Knitting-machines ; photo-electric apparatus. STANLEY, W. E., and EDWARDS, C. H. June 7, 1940, No. 9953. [Class 40 (iii)] [Also in Group VIII] The fabric knitted in a knitting machine is examined photo-electrically for transparency or reflecting power between the knitting needles and the take-up rolls, whereby any irregularity gives a signal or automatically stops the machine. As shown in Figs. 1 and 2, a mirror 9 is placed below the fabric 6 between the needles 1 and the take-up rolls 7, and a photo-electric cell 32 and a lamp 31 are supported above the fabric 6 by a carriage 29 slidably mounted on a slidable rod 28. The carriage 29 engages a part nut with a screw shaft 10 to which is splined a clutch member 26 adapted to be clutched alternately with opposite bevel wheels 22, 23 in mesh with a bevel pinion 21 on a shaft 20 driven through bevel gearing 19, 18 and belt gearing 16, 17, 15 by the hand-wheel 14 of the machine. The clutch member 26 is controlled by a fork 27 on the rod 28 in conjunction with end stops 34 also on the rod 28, as follows. While the clutch 26 is engaged with one of the two wheels 22, 23, the carriage 29 is driven in one direction across the fabric 6. On reaching the end of its stroke, the carriage abuts the stop 34 at that end and causes the rod 28 to slide and the clutch 26 to be engaged with the other of the two wheels, whereby the rotation of the screw shaft 10 is reversed and the carriage driven back across the fabric. The light reaches the photo-electric cell through a slit disposed lengthways of the fabric and long enough to ensure that each part of the fabric shall be tested twice. The photo-electric cell is connected to an amplifier adapted to give a signal or operate a stopping device if the increase or decrease of illumination on the cell is abnormal. The sensitivity may be varied by adjustment of the circuit or of the width of the slit. In a modification the photo-electric cell is situated just below the fabric exposed to general illumination above, and the cell is on a carriage guided on rails and reciprocated by alternate attachment to the opposite sides of an endless chain.

Filed: 1917-07-11
Abstract: 117,140. Hall, K. E. July 11, 1917. Cultivators.-A machine for pulverizing soil, adapted to be drawn by animal or mechanical power or propelled by its own engine, comprises a main frame 1, supported at the front on a leading wheel 2 and at the rear upon travelling wheels 3, which carries a pair of crushing rolls 6, 9 to which clods are fed by an endless band conveyer 20 which receives them from the tines 13 of a collecting member 14. The member 14 and the conveyer 20 are mounted on a pivoted frame 15, the inclination of which is adjustable by a screw 24. The rolls 6, 9 are driven from the wheels 3 and, to prevent breakages due to stones passing between the rolls, the roll 9 is resiliently mounted. The stones which pass the rolls may be caught in a grid-like collector 25. In a modification, the rolls may be formed of spring wire through the interstices of which the stones can pass. In another modification, the conveyer is omitted, the clods passing directly up an incline to the crushing-rolls. The Provisional Specification also describes modifications in one of which a single roll is used which works against yielding pressure-plates; in another modification, the tines of the scoop are arranged to let the fine soil fall without passing through the crushing-devices.

Title: Improvements in or relating to polarograph apparatus
IPC: G01N27/48
Filed: 1961-03-20
Abstract: 934,453. Polarographic apparatus. C. L. ROUGHTON. May 20, 1962 [March 20, 1961], No. 9996/61. Class 37. A transistor 12, Fig. 1, is interposed between a polarograph cell 14 and the cell current measuring resistance 16 to isolate electrically one from the other and to enable the voltage from a voltage sweep generator 10 to be applied effectively directly across the cell. The output from terminal 18 is applied to the Y plates of a cathode-ray tube. In a modification, Fig. 2, cell 14 is connected between the commoned emitters of two transistors 22, 24 and earth, 22 being an NPN type and 24 a PNP passing positive and negative waveforms respectively. The collectors of transistors 22; 24 are connected to the load 16 through PNP type transistor 26 and NPN type transistor 28, which have their collectors commoned and provide current amplification. An arrangement suitable for current sweep polarography in which the resistance is in the emitter circuit and the cell in the collector circuit is described with reference to Fig. 3 (not shown), an additional current being supplied to the cell through a further junction transistor at fixed emitter-base potential to achieve a suitable range of potential developed across the cell, and to avoid high amplitude current variations within the cell. Reversal of the positions of the cell 14 and resistor 16 in Fig. 2 for the purpose of achieving current sweep is also referred to. Compensation of the residual current flow through a cell is described with reference to Figs. 4-6 (not shown), compensation being effected by applying a square wave voltage to the base-emitter of a transistor including the cell in its collector circuit together with a triangular waveform applied to the cell via the base-collector path of a transistor. Alternatively, a compensating voltage waveform may be applied via a transistor whose collector is connected to the measuring resistor. In an arrangement, Fig. 7, in which the voltage is applied in discrete steps e, Fig. 8, the waveform is applied from a sweep generator 10 through resistors 34, 36 and transistors 22, 24, 38, 40 to cell 14, the connected commoned collectors and commoned emitters providing negative feed-back. The 10 kc./s. output from an oscillator 44 is modulated by the emitter currents or transistors 38, 40, to provide an alternating input to an amplifier 46, the amplifier output being demodulated and detected in a unit 48 for application to the Y plates of a cathode-ray tube. Gating circuits 52, 56 operated by a trigger circuit 54 enable a small portion of the steady state current to be observed, the region chosen being one at which the capacitive current has decayed to a steady value. Synchronization of cathode drop renewal with the application of the waveform is achieved by control of a solenoid striker mechanism through a control circuit 58 supplied also from the generator 10.

Title: Flat tube for heat exchanger and heat exchanger
Inventor: KOTO HIROSHI
IPC: F28F1/02
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of dew-flying phenomenon and permit the draining of condensate, adhered to a heat exchanger, efficiently by a method wherein a draining groove, staying and conducting the condensate to flow along the flat tube, is formed on at least the upper surface of the flat tube. in which a plurality of heat transmitting medium flow passages are provided. SOLUTION: Condensate, staying on the outer surface of an evaporator when heat transmitting medium is conducted to flow through the inside of a heat exchanger 4 and the heat exchanger is used as an evaporator, is pushed by air stream B and flows into a draining groove 3, formed at the downstream side, and is conducted sequentially to flow downward by the slope of the groove 3. In this case, the condensate is dropped into the draining groove 3 whereby the flow of drain will not be interferred by a corrugate fin 7 and can be separated from the air stream B thereby permitting the draining in spite of the increase of flow rate of the air stream B. Accordingly, condensate will not be grown to a large water drop at the downstream side of the air stream B of the flat tube 1 for the heat exchanger whereby the phenomenon of dew-flying can be prevented.
